In-Field and On-Site Services
- The Analytical Service Center can assist Investigators in some facets of their projects by providing sample processing in the field. Extensive field experience has provided
the lab with a suite of proven procedures and specialized equipment.
- Services provided include: Sample collection, filtration / fractionation,
and preservation. Direct field measurements can be provided, in cooperation
with technicians from the Physical Science Department, to include full physicochemical
water column profiles: STD, pH, DO, and pigments.
- For an hourly charge, ASC Technicians can come to your location to assist
in sample pre-treatment and preparation using your own facilities and equipment.
